I was trawling through posts and browsing the Internet when I came a cross this by Chris Monckton titled "Hockey stick? What hockey stick?" and it's about the ipcc climate change (warming/climate panic) papers and how global warming scenario was stated. Quite an interestin read, tell me what you tHink

Also if you have any links to research papers please post a link to them, there's so much knowledge to be gained from a lot of them.
Although this isn't a paper as such it's a good read, it's a SSW event list with animations

This next paper suggests that SSW's are more likely in ENSO event years rather than ENSO neutral years.
